SAFETY RAZOR BLADE HONING DEVCE Ella Schramm, Brooklyn, N. Y.Application November 25, 1952, Serial No. 322,511

3 Claims.

This invention relates to devices for holding the blades used in safetyrazors while they are being stropped or honed, or while being used forcutting material.

principal object ci the present invention is to provide a device whichwill rigidly hold the blade while it is being sharpened, or while it ismaterial, and in which the blade may be readily secured and released.

A further object of the invention is to provide a device of this ltindwith means ior supporting the blade holder at the proper angle relativeto the material being cut in order to facilitate the cutting oi thematerial.

A. still further object of the invention is to provide a device of thiskind which is readily convertible from a device for holding a razorblade while being sharpened, to a device for cutting material.

Another object of the invention is to provide a device of this kindwhich is compact, is characterized by fewness of parts, and is highlyeilicient in use.

It is a further object of the invention to construct a novel safetyrazor blade honing device which is simple and durable and which can bemanufactured and sold at a reasonable price.

For further comprehension of the invention, and oi the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in whi i thevarious novel features of the invention are more particularly set forth.

in the accompanying drawings forming a inaterial part of thisdisclosure:

Fig. l is a perspective view of a device for holding a safety razorblade while being sharpened, embodying one form of the invention, theblade being omitted.

Fig. 2 is a similar View showing the clamping plates in open positionand showing a blade in dotted lines.

Fig. 3 is a fragmentary longitudinal sectional view through the body ofthe device, one of the blade clamping plates being shown in elevationand the blade being shown in position.

Fig. Il is an enlarged vertical sectional view taken on the plane or"the line -d of Fig. l, with the blade clamped position.

Fig. 5 is a perspective 'View of a modied form ci" the invention shownin position for cutting material.

Fig. 6 is a fragmentary longitudinal sectional view of the form of Fig.5.

Fig. 7 is a side elevational View of the clamping 2 plate andpositioning plate of the form of Fig. 5, in disassembled position.

Fig. 8 is a similar View, but showing the positioning plate in extendedposition on the clamping plate.

Fig. 9 is an enlarged vertical sectional View taken on the plane of theline 9--9 oi Fig. 5.

Referring to the drawings, a blade holder made in accordance with theiirst forni of the invention shown in Figs. l to d, inclusive, comprisesan elongated tubular body lil of resilient sheet metal, substantiallycircular in cross-section. rThe body is formed with a razor bladeholding portion H at one end, the other end of the body being knurled onits outer surface as indicated at i2, and serving as a handle. The bladeholding portion is formed with an elongated slot i3 intersecting theopening at the end of the body.

A pair oi complemental resilient blade receiving and clamping plates itland i5 are mounted in the slot it. Each plate is substantially the sizeand shape of a conventional safety razor blade and is formed at one endwith a perforated ear I6. A transversely extending pivot pin l? extendsthrough aligned cpenings in the body lil and through the aligned ears itwhereby the plates are pivotally and independently mounted so that theymay be swung through the slot i3 subsequent to receiving a safety razorblade it. The other end of each plate is formed with an integralextension id, said extensions projecting through and beyond the open endof the razor blade holding portion Il so as to be readily engaged by thefinger of the user.

In the use of the device, the clamping plates l and l 5 are swungoutwardly of the blade holding portion Il so as to permit the plates tomove relative to each other. The razor blade i8 is then inserted betweenthe plates. The plates are then moved toward each other and swunginwardly of the slot I3, the resiliency of the walls of the slot causingthe plates to bind on the blade to prevent movement of the blade in anydirection relative to the holder. The blade is then ready for stroppingor honing, there being no danger of the blade slipping or becomingaccidentally displaced.

In the modied form of the invention shown in Figs. 5 to 9, inclusive,the tubular body i0', with its razor blade holding portion il andknurled handle portion I2', is constructed the same as the tubular bodylil of Figs. l to 4, inclusive. However, its clamping plate Ul is formedon its inner surface with spaced protuberances 20, 2| and 22, adjacentits top end, in line with the perforation in its ear I6. An elongatedpositioning and supporting plate 23 is interposed between the clamp-ling plates I4 and I5' and is provided with spaced openings 24, 25 and 26for receiving the protuberances on plate Ill'. 'Ihe spacing between theopenings correspond to the spacing between the protuberances. rTheplates I4 and I5 are adapted to clampingly support the razor blade I8with its cutting edge projecting therefrom.

In using this form of the invention, for sharpening the razor blade I8',the positioning and supporting plate 23 is supported on the clampingplate lll with the protuberances 20, 2i and 22 received in the openingsZd, 25 and 26, respectively, so that the outer end of the plate 23 is inalignment with the outer ends of the finger extensions I9 of the platesI and I5. The lower ends of the plates iii and I5' rigidly bind therazor blade for stropping and honing on a strap.

When it is desired to use the blade I8 of this form of the invention forcutting material, such as fabrics, paper and the like, the positioningand supporting piste 23 is projected outwardly and laterally of the ngerextensions I9' of the plates i4 and I5. This is accomplished by movingthe plate 23 along the clamping plate I4 and placing the openings 25 and2S over and in interlocking relationship with the protuberances 20 and 2I, respectively, on the plate ifi so that the outer end of said plate 23extends outwardly beyond the outer ends of the finger extensions i9', asshown in Figs. 5 and 8. When the positioning plate 23 is in thisextended position, the lower Ecorner of the outermost end of said plateserves as a guide to position the blade holding portion I I and bladeI8', at the proper angle for cutting the material. The corner of theplate 23 and the corner of the blade I8 serve as a two-point support forthe blade so that it is held in a steady position for cutting thematerial along a straight line.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope 0f the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

1. In a safety razor blade holder of the kind de scribed, a tubular bodyhaving an elongated slot at one end and a handle portion at the otherend, a pair of clamping plates pivotally mounted in the body forreceiving and clamping a safety razor blade therebetween, said platesbeing swingable through said slot, extensions on the ends of said platesprojecting through the open end of the slotted end of the body, spacedprotuberances on the inner surfaces of one of said clamping plates, andan elongated movable plate interposed between the plates within thebody, said elongated plate having spaced openings therein, the spacingbetween said openings corresponding to the spacing between saidprotuberances, whereby the movable plate may be shifted along theclamping plates and extensions and held in extended position beyond theouter ends of the extensions for positioning the clamping plates andsupported blade in proper angular position for cutting material with theblade.

2. A safety razor honing device comprising an elongated tubular body ofsheet metal, a safety razor blade holding portion formed at one end ofthe body, a knurled handle portion at the other end of the body, saidblade holding portion having an elongated slot, a pair of clampingplates pivotally mounted in said slot and adapted to receive and clamp asafety razor blade therebetween, extensions on one end of said plates,spaced protuberances on the inner surface of one of said clampingplates, an elongated movable plate interposed between said clampingplates and said extensions, said movable plate having spaced openings,the spacing between said openings corresponding to the spacing betweensaid protuber ances for receiving the protuberances, said movable platebeing normally positioned on said clamping plate with its outer endregistering with the outer ends of the extensions on said clampingplates, said movable plate being shiftable along the clamping plates soas to extend its outer end outwardly beyond the outer ends of theextensions on the clamping plates whereby the outer end of said movableplate serves to guide the plate holding portion to proper angularposition for cutting material with the blade 3. The combination of claiml wherein the movable plate is of a slightly lesser thickness than therazor blade.
